Summary

Thunder Mountain High School is a public high school in Juneau, Alaska, serving 586 students in grades 9-12. The school is part of the Juneau Borough School District, which is ranked 16 out of 24 districts in the state.

Thunder Mountain High School stands out for its diverse student population, with 48.63% White, 9.9% Hispanic, 7.34% Asian, 11.6% Native American, and 19.28% two or more races. This diversity is higher than the nearby Juneau-Douglas High School: Yadaa.at Kale, which has a 46.38% White student population. Academically, the school has shown strong performance in the past, ranking 7th out of 61 Alaska high schools in 2020-2021 and earning a 5-star rating from SchoolDigger. However, its ranking has declined in recent years, dropping to 31st out of 63 schools in 2023-2024 with a 3-star rating.

Thunder Mountain High School has performed well in serving certain student subgroups, such as Asian and Hispanic students, but has struggled with the performance of Native American students. The school has also faced challenges with its low socioeconomic status (SES) students, ranking 25th out of 41 Alaska high schools in 2023-2024. Addressing these disparities and the overall decline in academic performance will be key priorities for the school and district moving forward.
